====== Smartwatches ======

Similar to smartphones, but smaller, restricted in functionality even more, and on a wrist. Like the smartphones, these will usually run an ARM chip, and either WatchOS or Android Wear. A few of them are based off of more obscure architectures and OSes.

===== 2000s Watches (general) =====

==== Other ====
=== Fossil Wrist “PDA”, OnHand PC ===
Just a simple comparison table between two early 00s watch-esque PDAs. Apparently in 2005 the Fossil Wrist PDA has 4x the RAM of the OnHand PC.

===== Apple Watch =====

==== Other ====
=== Doom  ===
A very unoptimized port, but still, it is a functional port of Doom. WatchOS 2 is the version used?

===== Google Android Wear (General) =====

==== Operating Systems (varies) ====
=== Classic Mac OS 1.1-7.5.5 (in Mini vMac) ===
Runs very smoothly in the emulator. The video depicts version 6. Would be nice with a small stylus, or a bigger watch.

=== Emulation Nest ===
This device runs an operating system which is known to emulate various devices with EOPs. See the [[eop:operating_systems:conventional:classic_mac_os|Classic Mac OS]] and [[eop:operating_systems:conventional:dos|DOS]] pages.



=== Windows 3.1 and 95 (aDOSBox) ===
Windows 3.1 runs mediocre, while Windows 95 can barely even run applications. However, they do in fact run.

Just running some game APKs on the little Android Wear.

=== Media player ===
>Only software decoding players work

Using something called QQT player, and is smooth at low resolutions.

===== Huawei Watch =====

==== Operating Systems (Qualcomm APQ8026) ====
=== postmarketOS ===
>First build the image

Unsure if there’s more model info to this, past “Huawei Watch”. Touchscreen, flashing, and display all work, but of course, the output attempts to render itself in a square form factor. Other than that, the device functions on postmarketOS.

===== IBM Custom Watches =====

==== Operating Systems (Cirrus Logic EP7211) ====
=== Native Linux 2.2 ===
>successfully running Linux and X11

A custom research watch with full Linux functionality, alongside of course, being a watch. Lead to some PDA-esque “watches” in the early 00s.

===== LG G Watch =====

==== Operating Systems (Qualcomm APQ8026) ====
=== postmarketOS ===
>Turn on your watch and swipe from the top left corner

It boots, has touchscreen, Xwayland, and the accelerometer. Since this watch has a square screen, it probably features postmarketOS in a fashion superior to other smart watches.

===== LG G Watch R =====

==== Operating Systems (Qualcomm APQ8026) ====
=== postmarketOS ===
>UART is multiplexed on the USB port. The watch has five pads that are directly connected

Unlike the G Watch, the R means round. While it can still run postmarketOS, the circular screen makes it a lot less practical. Still, Xwayland, touch, booting, and so on all work.

===== LilyGO T-Watch =====

==== Other ====
=== Doom ESP32 Port ===
>This is a PlatformIO project

Not dependent on any sort of operating system, but a cool proof of concept nonetheless.

===== Mobvoi Ticwatch C2+ =====

==== Operating Systems (Qualcomm MSM8909) ====
=== postmarketOS ===

>WARNING: Doing this will delete ALL your data on the device, so backup all your data before continuing!

More fully featured than the Ticwatch Pro below. Has display function, WiFi, and a working touchscreen!

[[https://wiki.postmarketos.org/wiki/Ticwatch_C2%2B_(mobvoi-skipjack)]]

===== Mobvoi Ticwatch Pro =====

==== Operating Systems (Qualcomm APQ8009w) ====
=== postmarketOS ===

>When the image created with the downstream kernel is flashed onto the device works

A pretty basic smartwatch instance of postmarketOS. It does run on there, but there isn't even a display output yet. USB networking works!
